A Claim is the process of a worker checking out a message to perform
a task. Claiming a message prevents other workers from attempting to
process the same messages.

queue

A Queue is an entity that holds messages. Ideally, a queue is created
per work type. For example, if you want to compress files, you would
create a queue dedicated to this job. Any application that reads from
this queue would only compress files.

message

A Message is a task, a notification, or any meaningful data that a
producer or publisher sends to the queue. A message exists until it is
deleted by a recipient or automatically by the system based on a TTL
(time-to-live) value.
